The eBike Store in North Portland has become the first dealer in the country to stock the Self-Balancing Unicycle — a.k.a. SBU. The SBU is an electric-assisted unicycle with “advanced angle sensing electronics and software” that allows it to balance and “pedal” for you.

The SBU was invented by engineer Daniel Wood of Camas, Washington-based Focus Designs. I met Wood last week for an up-close look at his amazing invention. Wood, 31, was laid off a year ago from his job at U.S. Digital in Vancouver and has spent the last two years developing the SBU. A classic tinkerer, Wood had previously invented a remote-controlled Segway-like device he called, “Gimpy.”

Wood demonstrates.

No crank arms needed.

“I wanted to take the guts out of Gimpy and put it on a unicycle to see if it would work. I was the guy out in the parking lot on my lunch hour on a unicycle with 40 pounds of lead-acid batteries in my backpack… I was fumbling around, then all of the sudden I was riding. It was awesome!”

The SBU has come a long way since then and Wood is now looking for investors and dealers. He says it’s a simple, lightweight, and compact way to get around. The ideal users, according to Wood, are public transit riders, college students, carfree urbanites, truck drivers, tourists, and so on.

Unlike a standard unicycle, the SBU is easy to get the hang of. I’ve never been able to ride a unicycle, but in a few minutes, I was whizzing around on the SBU, feeling all futuristic and cool. It’s a strange sensation — you just sit on the seat, lean forward, and the SBU zips you around. Want to stop? Just roll your hips back and it stops. You don’t even pedal (there are no crank arms), you just sit and glide.

Wood took the SBU to the Interbike trade show in Las Vegas last year and said it was a huge hit. He’s also gained his share of notoriety thanks to an appearance on the Mythbusters TV show back in December. He’s sold about 26 of them so far. The current price is $1,499. Here are a few other specs and features:

Weighs 24 lbs.

Custom lithium-ion nano-phosphate battery rated for more than 1000 cycles.

Automatic fall detection shutoff switch.

Goes 10 mph and has a range of 10 miles.

Folded size is 13″x20″x35″.

As our transit network expands, SBUs might appeal to the many people who will live a long walk from their transit stop. Will these things be the hot ticket in Portland? What do you think?

You can try one out at The eBike Store at 201 N. Alberta Street (on N. Vancouver Ave.). Check out the video clip below from Mythbusters to see it in action:

I vaguely remember a couple stories dating back a year or so ago about similar machines. The person reviewing one of them said it was a little challenging to get the hang of riding it. The other was a Japanese designed, slick, modernistic, white monotone rig. Really expensive too.

This one looks so simple and functional. Could use fold up pedals. The price is good. The speed is good. I would think these things have great sales potential.

Daniel is going to have a self balancing unicycle (SBU) placed at Serious Juggling for people to try too! And yes, the SBU was a quite the hit at Interbike – the first comment most people made when they saw we sell unicycles was, “Have you seen that new self balancing unicycle?”

1) Yes, it comes with a charger and can easily plug into a regular outlet (110v or 220V when favorable winds take you to the South Pacific)

2) Coffee Holder is plausible. I would wait until you are good at it to try carrying too much cargo – it tweaks your balance. I had a heck of time commuting home with my chrome bag full of books / computer. (I might be sending this from a recently cracked laptop…)

3) Wiggle charging is not available at this time. However, you will get a core workout as you get your balance muscles up and working!

As usual, we have free latte’s.and are open 11-6:30, Weekends 10-5. Mon/Tues is my weekend. You can stop by, but no one will be there…

Way cooler than a Segway. But I’ll be really sold when I can add some pedaling muscle. I want to provide (most of) the energy and it to help me balance and maybe serve as an infinitely-variable-transmission.

Andy #14, your Brompton seems like a cool engineering exercise, but doesn’t seem to serve any real purpose. I have a 1976 BMW R90/6 motorcycle. It goes 100mph, can go on the highways, gets stares from people and never needs charging. Plus it can carry a heck of a lot of cargo and will probably run for another 35 years.

Progress is so cool as I type this on my iPhone we barely have to think, walk, talk, etc cool video better than driving a car unnecessarily probably a fad or ?? Gimmick certainly not electric-assist more like a wheelchair
